A banneton is the round or oval proofing basket that gives sourdough its final shape and that signature spiral of flour ridges on the crust. Get the basket right and your dough proofs evenly, releases cleanly, and holds structure through the final rise. Get it wrong and you're prying dough off cane at 5 a.m. while your oven sits at 500°F waiting.

This guide covers what to buy, how to break a new one in, and how to keep it usable for a decade. I still use a rattan banneton I bought in 2018 — it's on maybe 400 bakes and looks better than the day I got it.

What a banneton actually does

Three jobs, in order of importance:

  1. Holds shape during the final proof. A well-shaped boule slackens as it ferments. Without support, it spreads into a puddle.
  2. Wicks moisture from the surface. A slightly drier skin scores cleanly and colors better in the oven.
  3. Leaves a decorative flour pattern. Cosmetic, but it's what people associate with "real" sourdough.

The wicking part is why material matters. A plastic bowl lined with a floured towel will hold shape but leaves the crust damp and pale. Rattan, cane, and unfinished wood pulp all pull moisture out. That's the difference.

Choosing a banneton: material and shape

Rattan (cane)

The classic. Coils of rattan bound in a spiral. Wicks well, leaves the deepest ridges, lasts decades if you treat it right. Downside: dough sticks easily until the basket is properly seasoned, and the coils can trap flour and old dough if you're careless.

Wood pulp (paper composite)

Sold as "German" or "Brotform" style, sometimes marketed as "no flour needed." They're smooth, nearly nonstick out of the box, and produce a clean surface with no ridge pattern. Good for beginners who are tired of dough sticking. They don't wick as aggressively as rattan and they'll warp if you soak them.

Cloth-lined baskets

A plastic or wicker frame with a sewn linen liner. Nearly nonstick. No ridge pattern (unless you remove the liner). Machine-washable liner. My pick for anyone who bakes rye or very high-hydration doughs above 80% where cane bannetons become a wrestling match.

Which shape?

Round (boule) is the default and handles most doughs well. Oval (batard) gives you a longer loaf that fits standard sandwich slicing and roasting-pan Dutch ovens. If you're buying one, get round first — most recipes are written for it.

Type Wicking Sticking risk Ridge pattern Best for
Rattan Excellent High until seasoned Deep, defined Classic country loaves, 70–78% hydration
Wood pulp Moderate Low None Beginners, smooth crusts
Cloth-lined Low–moderate Very low None with liner High hydration, enriched, rye

Sizing

Match the basket to the dough weight, not the other way around. Rough guide:

  • 500 g dough → 8" (20 cm) round or small oval
  • 750–900 g dough → 9" (23 cm) round or 10" oval
  • 1000 g+ dough → 10" (25 cm) round or 11" oval

An undersized basket makes the dough dome up and spill over. Oversized and the loaf spreads flat and never fills the shape. If you're using an online dough calculator to scale a recipe, check the final dough weight before you buy — I've seen people order a 10" basket for 600 g of dough and wonder why their loaves come out squat.

Seasoning a new banneton

New rattan is sticky. The cane is bare, dough grabs into every crevice, and you'll lose your first loaf if you don't prep it. Here's what works:

The break-in method

  1. Mist the interior lightly with water. Not soaked — just damp enough that flour will cling.
  2. Dust heavily with a 50/50 mix of rice flour and all-purpose flour. Rice flour is the key. It doesn't absorb water the way wheat flour does, so it stays on the surface as a barrier layer.
  3. Rub the flour into every coil with your fingers. Push it into the grooves.
  4. Tap out the excess. The basket should look powdered white, not caked.
  5. For the first 3–4 bakes, use extra rice flour. After that, the basket develops a patina and needs less each time.

Skip the olive-oil-seasoning advice you see online. Oil goes rancid, attracts dust, and doesn't actually help release. Flour does.

Why rice flour matters

I learned this the annoying way. First banneton, first bake, dusted with bread flour like the recipe said — dough welded itself to the cane. I chipped it off with a bench knife. Next bake I switched to rice flour, same dough, same basket. Slid out clean. If you take one thing from this article, it's that: keep a small container of rice flour next to your banneton and use nothing else for dusting.

Using it correctly

  • Dust before every use, even a seasoned basket. A light layer of rice flour in the coils.
  • Place the dough seam-side up. The smooth side that will face down in the oven should face down in the basket. The ridges form on what becomes the top of the loaf.
  • Cover during proof with a shower cap, plastic bag, or damp towel to prevent skin-drying.
  • Cold retard in the fridge is fine — the basket handles temperatures down to 35°F without any issue. Uncovered retards give you an even drier, more scorable surface.
  • Turn out gently. Invert onto parchment or a peel with a quick, decisive motion. Hesitation causes tears.

Cleaning a banneton

This is where most bakers go wrong. Do not wash a rattan or wood-pulp banneton with soap and water.

Cane absorbs water, swells, and can grow mold if it doesn't dry fully. Soap residue transfers to future doughs. What you want instead:

After every bake

  1. Let the basket air-dry completely, upside down, for 24 hours. Any stuck dough will harden.
  2. Bang it firmly against the counter or sink to knock out crumbs.
  3. Brush with a stiff dry pastry brush or a clean paint brush to remove flour buildup from the coils.
  4. Store uncovered in a dry cabinet. Not in a plastic bag — trapped humidity is how mold starts.

Deep clean (every 20–30 bakes or when it looks grimy)

  1. Scrape out any hardened dough with a wooden skewer or bamboo pick.
  2. Rinse briefly under lukewarm running water — no soap, no soaking.
  3. Blot with a towel.
  4. Air-dry for at least 48 hours in a warm, ventilated spot. A sunny windowsill is ideal.
  5. Once bone-dry, re-season with rice flour before your next bake.

If you see mold

Small spots: rinse under hot water, dry in a 200°F (95°C) oven with the door cracked for 30 minutes, and re-season. Extensive mold or a musty smell that persists: replace the basket. It's not worth risking a bake.

Common problems and fixes

Dough sticks in patches. Not enough rice flour, or the basket wasn't fully dry from last use. Dust more aggressively and let it dry longer between bakes.

Ridge pattern is faint or missing. Either the dough was underproofed (didn't push into the coils) or overproofed (too slack to hold the impression). It's also worth checking whether you have too much flour caked in the grooves — clean it out.

Basket smells sour. Trapped moisture. Bake it at 200°F for 30 minutes and let it fully cool. Store somewhere with airflow.

Cane fibers loosening. After a few hundred bakes some coils fray. A dab of food-safe wood glue on the frayed end, clamped for an hour, will hold for years.

Common questions

Do I really need a banneton?

For any dough at 70%+ hydration proofing more than 90 minutes, yes. Below that — a stiff 65% dough proofed briefly — a floured towel in a bowl works. But the moment you push hydration or extend the final proof, the towel-in-a-bowl trick fails.

Can I proof directly in a bowl without a basket?

You can, and it'll work for stiff doughs. You lose the wicking and the ridge pattern, and dough is more likely to stick to the towel than to a properly seasoned banneton. Bakers who tell you a bowl is "just as good" haven't compared them side by side.

How long does a rattan banneton last?

With proper care, 10+ years and hundreds of bakes. Neglected, six months. The failure mode is almost always moisture — either soaking to clean, or storing damp.

Can I put it in the dishwasher?

No. The heat, the detergent, and the extended soak will destroy any wood-based basket in a single cycle. Cloth-lined bannetons: remove the liner and machine-wash cold, air-dry. The frame stays out of water.

Should I flour the dough or the basket?

Both, but differently. The basket gets rice flour rubbed into the coils. The dough surface — the top when it's in the basket, which becomes the bottom of the loaf — gets a light dusting of whatever flour you like. If you're building a decorative flour design on the loaf top (which is the dough side facing the basket coils), dust the basket generously right before the dough goes in.

Is there any point to buying an expensive banneton?

Mostly no. A $15 rattan basket from a decent supplier performs identically to a $40 one. What matters is that the coils are tight and even, and the rim is bound so it won't unravel. Check reviews for basket wobble and loose coils — that's the actual quality difference.

The one habit that matters most

If you take nothing else from this: after every bake, flip your banneton upside down on a wire rack and leave it there for a full day before storing. Nine out of ten banneton problems — mold, sour smell, dough sticking, cane deterioration — trace back to putting away a basket that wasn't fully dry. Everything else is optimization around that one habit.
